fyi, just in case ...
i own an old Benq fp241 with picture in picture, so newer monitor might be better .
pip is fine but not really practical, the pip doesn't work for all types of connections of the monitor.
but the biggest problem is that the placement on the pip is only reacheble with the monitor buttons and are deep in the menus... and of course pip is allways "on top" without transparence etc etc ...
i really prefer a tuner card inside my pc, who gave me a tv and to whom i can connect other video sources , that tv window can be manipulate like any other windows ! much much better!
i used time to time my pip for some strange vga signal coming from old and embedded computers but for me it not that practical to use it has a tv...
